LIQUID-FUEL BURNER.

' Specification of Letters Patent.

Application filed November 25, .1911. Serial No. 662,494.

, Patented Jan. 7,1913.

such burners which are designed to be ar-- ranged within thefire-box of an ordinary cooking range, heating stoves, and furnaces, and the burner embodying the present invention is designed as an improvement on. the burner shown in the application filed May 26, .1911, Serial No. 629,678.

One aim of; the invention is; to provide against waste of liquid fuel and to provide novel meansfor vaporizing the fuel, this means embodying essentially a vaporization coil which is disposed within the pan of the burner below-the mixer-tube and i-sheated by jets of flame issuing from the mixertube, whereby to, vaporize the fuel prior to its admissionv into the burner-tube. V

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which 7 p Figure 1- is a view in elevation of the burner embodying the present invention, the pan being shown in longitudinal section. Fig. 2 is a top plan view of the burner. Fig. 3 is avertical transverse sectional view 0 the line 33 of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

In the drawing, the burner-pan is indi-' cated in general by the reference numeral 1, and is preferably rectangular in form and includes an imperforate bottom 2, front and rear walls 3 and 4 respectively, and endwalls 5. The burner includesa mixing tube which is indicated'by the numeral 6 and is formed in its under side with slits or openings 7 from which issue jets of vaporized fuel mixed with air. This tube 6 is closed at one end and mounted through one endwall of the pan 1 and secured in place by means of a collar 8 and bolts 9. At its other end, the tube extends through the other endwall of the pan 1 and the series of openings 7 in the tube terminates short of this last mentioned wall, the projecting portion of the tube at this last mentioned end being imperforate, as clearly shown in Fig.1 of the.

drawing. I

It will be observed by referring to Figs. 1 and 2 that the tube 6' is spacedabove the bottom of the pan 1. The burner tubeis indicated by the numeral 10 and is supported above the mixer-tube 6 by' means of a short union 11 which serves also to establish communication between the mixertube 6 and the burner-tube 10. The union 11 is preferably connected with the burner and mixer-tubes at points substantially midway between their ends, and the burner tube 10 is formed with slits or openings 12 in its upper'side through which a mixture of vaporized fuel and air issues.

In order that the fuel may be vaporized before being fed to the mixing tube 6, there is provided a vaporizing coil which is 10- cated within the pan below the mixer tube 6, and this coil is indicated by the numeral 13 andconsists of a pipe of a suitable size coiled uponfitself several times, as shown in Fig. 3 of the drawing. A vaporization chamber114: is interposed in one ofthe coils of'the pipe 13 .and beyond this chamber the pipe extends-through that end-wall of the pan through which. the mixer-tube 6 extends, and carries a cut-off valve 15 which "controls the supply of fuel thereto, the fuel being fed to the pipe through a tube 16 lead ing from a fuel tank 17, and thefuel being forced from this tank by an air pump 18. The other end of the pipe 13 is also extended through said wall of the pan, preferably at a point below the mixer-tube 6 and extends beyond the open end of the projecting portion of this tube, as clearly shown in Figs. 1 and 2 of the drawing. At its said end, the pipe 13 is extended upwardly as at 19 and communicates with a nozzle 20, but has its discharge end.21 presented at the open end of the mixer-tube 6.

The burner above described is designed to have its pan and the elements associated with the pan, disposed within the fire-box of anordinary cooking range, and in using the burner, the valve 15 is first opened so as to allow the fuel from the tank 17 to run into the coil 13 of the vaporization chamber 14:. After passing through the coil, the fuel is discharged in its liquid state from the nozzle 20 into the mixer-tube 6 and as it escapes from the openings 7 of this tube, is a ignited. The jets of flame issuing from the tube impinge upon the bottom of the pan and serve to so thoroughly heat the coil 13 and the vaporization chamber 14 as to vaporize the fuel, so that in a comparatively short time the fuel will issue in a gaseous state from the nozzle and be discharged tube supported within the pan and extending at one end through one wall of the pan and having its said end open, a burner tube supported above and in communication with the miXer-tube,the mixer-tube having discharge openings presented toward the bottom of the pan, and a fuel supply pipe coiled Within the pan and having one end extending through the said wall of the pan and arranged to discharge fuel into the said mixer-tube.

2. In a liquid fuel burner, a pan, a mixertube supported within the pan, a burnertube supported above and in communication with the miXer-tube, the mixer-tube having discharge openings presented toward the bottom of the pan and being open at one end, and a fuel supply pipe having a portion of its length arranged within the pan beneath the mixer-tube and having its discharge end positioned to discharge fuel into the said mixer-tube.

8. In a liquid fuel burner, a pan, a mixertube arranged Within the pan and having discharge openings presented toward the bottom of the pan, a burner tube in communication with the mixer-tube, the said mixer-tube being open at one end, a fuel supply pipe having a portion of its length arranged within the pan below the mixertube, a vaporization chamber interposed in the said length of the fuel-supply pipe, and a nozzle supported atthe end of the supply pipe and arranged to discharge into the mixer-tube.

4:. In a liquid fuel burner, a pan, a mixertube arranged Within the pan and having one end extending through one wall of the pan and open, a burner tube supported above the mixer-tube, a union establishing communication between the burner and mixer-tubes, the mixer tube being formed with openings in its under side for the discharge of fuel, a fuel-supply pipe leading through one wall of the pan and coiled beneath the mixertube and between the same and the bottom of the pan, the said supplypipe leading beyond the coil, through the said wall of the pan and to a point in advance of the open end of the mixer-tube, and a nozzle carried by the last mentioned end of the supply pipe and arranged to discharge into the said mixer-tube.

In testimony whereof we afiix our signatures in presence of two witnesses.
